String Theory

I think the things about string theory is very cool... If our whole universe is just a piece of string, then we might have someway to go to the other universe because we are connected! I think then if we can travel to other universe then we don't need to worry about environmental problems anymore unless we still need to live here even though we can travel to somewhere else. For me, I don't think it's easy to figure out the whole string theory.. Can we twist our universe and change like the condition or something? Can we find out a way to go to the other pieces of strings? That will be cool. If we traveled to other string, does that means we time traveled? There are still lots of thing for "me" to understand this theory...
